Filter by:According the Maastricht IV consensus report publish in the Gut 2012, bismuth containing quadruple therapy was suggested to be the first choice for eradication therapy of Helicobacter pylori in the area with high clarithromycin resistance. Whether hybrid therapy or 14-day bismuth containing quadruple therapy can replace standard triple therapy as the recommended first-line treatment is unknown. The investigators compared the efficacy of 14-day hybrid therapy and 14-day bismuth containing quadruple therapy in first-line treatment.
Dexlansoprazole MR is the R-enantiomer of lansoprazole that is delivered by a dual delayed release formulation. It is effective for symptom control of patients with gastroesophageal reflux disease. However, its efficacy in the treatment of H.pylori infection remains unclear. This study was conducted to investigate whether the efficacy of single-dose dexlansoprazole MR-based triple therapy was non-inferior to double-dose rabeprazole-based triple therapy in the treatment of H.pylori infection.
The Exalenz Dual Mode BreathID® Hp System comprised of IDkit: Hp™ TWO and the Dual Mode BreathID® Hp test device will be used to perform a urea breath test in the initial diagnosis and post treatment monitoring of H.pylori infection in adult patients and its results will be compared to biopsy results.
Up to now, there is few randomized, large scale study prospectively and simultaneously comparing the efficacy, adverse effects and patient adherence of high-dose dual therapy (HDDT) and bismuth-containing quadruple therapy (BQT) as rescue regimens for H. pylori eradication. The aims of this study are: 1. to compare the efficacy of HDDT, and BQT as rescue regimen in H. pylori eradication; 2. to compare the patient adherence and adverse effects of these treatment regimens; 3. to investigate factors that may influence H. pylori eradication by these treatment regimens.
Up to now, there is few randomized, large scale study prospectively and simultaneously comparing the efficacy, adverse effects and patient adherence of high-dose dual therapy (HDDT) and bismuth-containing quadruple therapy (BQT) as 1st-line regimens for H. pylori eradication. The aims of this study are: 1. to compare the efficacy of HDDT, and BQT as 1st-line regimen in H. pylori eradication; 2. to compare the patient adherence and adverse effects of these treatment regimens; 3. to investigate factors that may influence H. pylori eradication by these treatment regimens.
The study aims to evaluate H. pylori eradication rate in diabetic patients by using novel 10-day levofloxacin-based concomitant therapy compared with conventional 10-day sequential therapy.
This study evaluates whether Helicobacter pylori eradication improves precancerous lesions including glandular atrophy and intestinal metaplasia as well as metachronous cancers or dysplasias after endoscopic mucosal resection for gastric cancer.
New generations of fluoroquinolones, like levofloxacin and moxifloxacin, exhibit a broad-spectrum activity against Gram-positive and Gram-negative bacteria, and have been successfully introduced into the treatment of Helicobacter pylori infection. However, it was suggested that resistance to fluoroquinolones has been increasing in the Korean population and the resistance is most likely mediated through point mutation in gyrA. Gemifloxacin (FACTIVE®) is an enhanced-affinity, broad-spectrum fluoroquinolone suitable for once-daily, oral dosing. In vitro studies have shown that gemifloxacin displays potent activity against Gram-positive organisms, whilst retaining good activity against Gram-negative organisms. Gemifloxacin is the most potent member of the quinolone class against S. pneumoniae with activities 16-64 times greater than those of ciprofloxacin and ofloxacin and 2-8 times greater than those of moxifloxacin. Importantly, gemifloxacin displays potent in vitro activity against strains of S. pneumoniae with known resistance to β-lactams, macrolides and other members of the quinolone class. This potent activity is believed to be due to the enhanced affinity of gemifloxacin for topoisomerase IV, the major fluoroquinolone target in S. pneumoniae. Furthermore, gemifloxacin displays potent activity against H. influenzae and M. catarrhalis and atypical organisms such as L. pneumophila, C. pneumoniae and M. pneumoniae. It has proven particularly effective in respiratory and urinary tract infection.
1. To compare the diagnostic accuracy of the 13C-Urea breath test between using the citric acid as test meal and controlled group by endoscopic biopsy methods(histology, CLOtest and H. pylori culture). 2. To compare the delta value of 13CO2 results between before and after ingestion of citric acid as test meal.
Reverse hybrid therapy is a one-step two-phase treatment for Helicobacter pylori infection with less cost than standard triple therapy. Whether reverse hybrid therapy can replace standard triple therapy as the recommended first-line treatment is unknown. The investigators compared the efficacy of 12-day reverse hybrid therapy and 12-day standard triple therapy in first-line treatment.
